This invention relates to the method of constructing the walls and roof of that type of sectional oven which is especially suitable for baking japan or enamel upon metal articles.

The invention is designed to provide the oven with inner and outer panels arranged in parallel formation and stagered in relation to each other so that the eat from the 1nterior of the oven cannot escape through the joints of the outer panel.

A n object of the invention` is to provid each panel with insulation such as apacking of asbestos to prevent loss of heat and the asbestos of an inner panel is adapted to face the asbestos of an outer panel thereby entirely covering the binding members whereby the panels are locked or keyed together. I

The invention resides more particularly in the novel combinations hereinafter described and claimed, reference being made to the ac- ,companying drawing in which:

Fig, l represents avhorizontal section showin the side wall construction.

f' iig. 2 is a vertical section of a roof con-A struction. 1

Fig. 3 is a perspective view of a panel.

In the drawing is shown a metal panel having a back 5 provided with side rims 6' and endmembers 7 to form an open box like receptacle or compartment containing a nonheat conducting lling 8 such as asbestos. The rim has members 9 bent at right angles to the sides to prevent the asbestos from dropping out of the receptacle and provide r1- 'gidity or support for the binding members 10 which lock the panels together. One panel is similar to the other and as indicated in Fig. 1 the vertical side and end walls of the oven are constructed by placin alon side of each other in two rows one be d t e other any number, of the panels t form the inner y and outer walls.

In this arrangement the panels are engiged by H shaped binding members 10 eac coacting with thel side rim 6 of two panels placed side by side thus joining the panels together tolobviate inner or outer movement. There can be any number of the panels connected together depending on the size of the oven. The anels of the sides and ends are joined l t ier by means of corner sections 11 pack with/asbestos 12 yand havin reduced portions 14 to fit the thickness o the inner and outer panel sections.

The outer panels are placed with the asbestos facing the asbestos of the inner panels and the anel as indicated in Fig. 1 is in staggered re ation with the two panels behind it..

he panels of one row substantially cover the panels of the other. row and the parts of the inding connections where they Vcontact with the rims ofthe panels a're entirely covered by the asbestos.` '.lhe two rows of panels ro vide a simple and efficient way of buil ing the walls of a large oven and at the same time any of the sections can be removed for repairs or the oven can be entirely taken apart for transportation.

The roof section 15 as indicated in Fig. 2, consists of an inner and outer row of panels similar to the panels of thegwall sections and one is longer than the other to provide stepped portions 16 to fit the end rims of the side walls. The panels carry a packing of asbestos 17 entirely covered by the" plates of the panels when locked together. The corner joint is covered by means of a woven strip of asbestos 18 while an angle. iron 19 superimposed on the asbestos prevents outward throw of the panels. When the panels are in place the metal seals the asbestos and dust or any other foreign matter cannot enter the vcompartment to mingle with the asbestos.

Any number of the roof panels can be arranged side by side in staggered formation depending on the size of the oven. In order to kee the ends of the roof and side panels from ing displaced or shifting inwardly angle irons 2O secured to the back of the panels can be employed.

I claim:

1. A sectional oven wallcomprising a plurality of inner and outer panels one behind the other the meeting ends of the'outer panels being covered by the panels behind them each panel having a packing of insulating material, and means relative to each pair of panels for locking them together.

2. A sectional oven Wall comprising an inner and outer row of panels one behind the other the meetingends of the outer panels being covered by the panels behind them each panel having a packing of insulatin material, and means relative to each pair o panels in a row for locking them together.

3. A sectional oven wall comprising an inner and outer row of panels one behind the other each panel having a packin of insli-l latin material the meeting ends o the outer lpane s being coveredby tlqpanels behind them, and bindin each pair of pan them together.

4. A sectional ove-n wall comprising aninner and outer row of panels one behind the other each panel havin a packing of insulatin material the pac ing of one row facing t e packing of the other row the meetin ends of the outer panels being covered by the panels behind them, and binding inembers coacting with eacl pair of panels in a row for connecting the together.

5. A sectional oven `wall comprising an inner and outer row of panels one behind the other each panel having a packing of insulatini material the packing of one row fac ing t e packing of the other row the inner panels being arranged in staggered formation relative to the outer panels thereby covmembers coacting with s in a row for connecting erin the joints of the inner panels, and binding members coacting with each pair of panels along side of each other in a row for connecting them 4to ether.

6. A Wall unit suitable for a sectional oven comprising a panel having a back provided with a rim forming an uncovered receptacle, and a non-heat conducting insulating material contained in the receptacle.

7 A Wall unit suitable for a sectional oven, comprising a panel having a back with side rims each rim includin a member disposed at an angle thereto an end members forming an uncovered receptacle, and a non-heat conducting insulating material contained in the receptacle.

In testimony whereof I have hereunto set m hand.
